diff

The diff command in Linux is used to compare two files or directories and show the differences between them. It is a powerful tool that can be used to find differences between files, to check for changes in files, and to merge changes from one file into another.

The diff command is used in the following syntax:

diff [options] file1 file2

The file1 and file2 are the names of the files that you want to compare.

The options can be used to specify the following:

• -b : Ignore blank lines.

• -c : Show the context of the differences.

• -u : Show unified diff.

• -I : Ignore lines that match the regular expression.

For example, the following code will compare the files file1.txt and file2.txt and show the differences between them:

diff file1.txt file2.txt

This code will print the differences between the files file1.txt and file2.txt to the standard output.
